In newer [GHC 3.8.*](haskell/cabal#9326 (comment)) default directory for package DB storage has been changed to include "ABI tag". So instead of `~/.cabal/store/ghc-9.8.4` it is now located at `~/.cabal/store/ghc-9.8.4-inplace` (when built with our scripts) or may use any other suffix (`ghcup` version of ghc for example has tag `-c895`. This messes up `%cabal_configure` macro as we have to pass package DB location explicitly with `--package-db`. However, correct GHC id (including ABI tag) can be obtained with command `ghc-pkg field ghc id`, which works both for current GHC 9.4.8 in repos and for 9.8.4 as well. For GHC 9.4.8: ```bash $ ghc-pkg field ghc id id: ghc-9.4.8 ``` For GHC 9.8.4 (built with our scripts): ```bash $ ghc-pkg field ghc id id: ghc-9.8.4-inplace ```

Summary
In newer GHC 9.8.*
default directory for package DB storage has been changed to include "ABI tag".
So instead of
~/.cabal/store/ghc-9.8.4it is now located at~/.cabal/store/ghc-9.8.4-inplace(when built with our scripts) or may useany other suffix (
ghcupversion of ghc for example has tag-c895.This messes up
%cabal_configuremacro as we have topass package DB location explicitly with
--package-db. However,correct GHC id (including ABI tag) can be obtained with command
ghc-pkg field ghc id, which works both for current GHC 9.4.8 in reposand for 9.8.4 as well.
For GHC 9.4.8:
For GHC 9.8.4 (built with our scripts):
Test Plan
Verify that reverse-dependencies of
